黔北煤田林华井田煤炭资源丰富，煤变质程度高，以无烟煤为主，煤层气含量高。通过井田煤田地质勘查成果及煤层含气量分析了主要可采煤层含气性分布及主控因素，并编制了主要可采煤层含气性分布等值线图，对煤层气资源量进行了估算。认为煤层埋藏深度和向斜构造是煤层气分布差异的主因，并获得主要可采煤层的煤层气资源总量为28.03×108 m3，煤层气开发前景较好。

The Linhua minefield in Qianbei coalfield has abundant coal resources with high degree of coal metamorphism, mainly an?thracite and high content of CBM. On the basis of minefield coal geological exploration results and CBM content analysis analyzed main mineable coal seams gas bearing property distribution and main controlling factors. Then compiled the main mineable coal seams gas bearing property distribution isogram and estimated CBM resources. Considered that the coal seam buried depths and syncline struc?ture are main factors to impact CBM distribution differences. Finally total CBM resources of 28.03 × 108m3 in main mineable coal seams have obtained, thus a better CBM exploitation prospect.
